The fabrication of polymer-nanoparticle composites is extremely important in the development of many functional materials. Identifying the precise composition of these materials is essential, especially in the design of surface catalysts, where the surface concentration of the active component determines the activity of the material. Antimicrobial materials which utilize nanoparticles are a par...

Nearshore rhythmicity is often initiated in the period just after a storm where the subtidal bar is turned alongshore uniform. The initiation time as well as the length scales of the created rhythmicity varies from one storm period to another. Here we show that the post-storm wave conditions are related to the initiation of the morphological rhythmicity. Narrow-banded and long wave period, both...

Global observations of ocean swell propagation is presented and analyzed, using on four years of satellite Synthetic Aperture Radar data. Tracking swells along their propagation paths yields an estimation of the dissipation of their energy. Swells can be very persistent with energy e-folding scales exceeding 30,000 km. For increasing swell steepness, this scale shrinks down to 2700 km, revealin...

ABSTRACT: In this paper, a simple mathematical model is proposed to predict the swelling behavior of an expansive soil from Saudi Arabia. The model consists of one equation with many parameters. The main advantage of this model is that only one parameter is needed to run the model. While the other model parameters can be determined using the best fitting curve technique. The testing program inc...

BACKGROUND/AIMS Phagocytosis depends on the formation of engulfment pseudopodia surrounding the target. We tested in microglia, monocyte-derived cells in the brain, whether a swelling-activated Cl(-)-current (I(Cl,swell)), required for global cell volume (CV) regulation, also contributes to local expansion and retraction of engulfment pseudopodia. METHODS We used scanning electron microscopy ...

S U M M A R Y The Cape Verde mid-plate swell is the largest amplitude oceanic mid-plate swell on Earth at ∼1800 km in diameter, with a crest ∼2.2 km high, and long-wavelength positive geoid, gravity and heat flow anomalies of 8 m, 30 mGal and 10–15 mW m−2, respectively. These characteristics and its location on the slow moving-to-stationary African Plate, which concentrates the volcanism and as...

Abstract With the continuous development of dredging business to overseas markets, ships are faced with a more and complex hydrodynamic environment. Swell long wave periods has great impact on adaptability ship operations. Focused Trailing Suction Hopper Dredger (TSHD), this paper studied motion response characteristics TSHD under influence swell. The result shows that is severely affected by a...

We present a new resource for Swedish, SweLL, a corpus of Swedish Learner essays linked to learners’ performance according to the Common European Framework of Reference (CEFR). SweLL consists of three subcorpora – SpIn, SW1203 and Tisus, collected from three different educational establishments. The common metadata for all subcorpora includes age, gender, native languages, time of residence in ...

Neuroendocrine (NE) differentiation of prostate epithelial/basal cells is a hallmark of advanced, androgen-independent prostate cancer, for which there is no successful therapy. Here we report for the first time on alterations in regulatory volume decrease (RVD) and its key determinant, swelling-activated Cl- current (I(Cl,swell)), associated with NE differentiation of androgen-dependent LNCaP ...

This work presents the development of a weakly compressible smoothed particle hydrodynamics (WCSPH) model for simulating two-dimensional transient viscoelastic free surface flow which has extensive applications in polymer processing industries. As an illustration for the capability of the model, the extrudate or die swell behaviors of second-order and Olyroyd-B polymeric fluids are studied. A s...
